[PATCH 0/2] mmc: add unstuck function if host is in deadlock state

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre@xxxxxx>

As discussed in this thread: https://patchwork.kernel.org/patch/10786421/
After a request, the host could be in deadlock state, and waiting
for a specific action to unstuck the hardware block before
resending a new command. This series adds mmc_hw_unstuck
callback (structure mmc_host_ops) before resending a new command
(call in mmc_blk_mq_rw_recovery, mmc_wait_for_req_done).
